ktest: Add MAX_MONITOR_WAIT option
If the console is constantly outputting content, this can cause ktest to get stuck waiting on the monitor to settle down. The option MAX_MONITOR_WAIT is the maximum time (in seconds) for ktest to wait for the console to flush. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
